In general, a bicycle lock requires two hands to operate. However, in real life ,whenever we are holding something in one hand, using another hand to lock a bicycle becomes a fairly difficult task. It is from this problem that the idea of the one-hand lock comes. By using the principle of a magnet’s attraction to iron and simple mechanical theory, the function of lock and unlock by a single hand can be easily achieved. Slightly push the lock to hold on to the tire, then scramble the passcode and then it will be locked; to unlock it, just simply dial the right passcode and pull out the lock. The operation is very simple and convenient.
